BENJAMIN OGUSH, OF NEW YORK, N. Y., ASSIGIIOR IO KAT-Z 8c QGQSI-I, I1 \TC. OF NEW YORK, N. Y., A CORPORATION or new 203 FASTENING DEVICE FOR WRIST WATCHES.

Application filed April 27, 1928. Serial NO. 273,224

This invention relates to an improvement in a fastening device for holding the wristsurrounding member of a wrist watch in position. It has for its object to providea form of clasp which will be particularly applicable for use upon a cordtype of wrist band.

The structure produced according to my invention is one of simple construction and few parts thus being extremely unlikely to get out of order, at the same time affording a very firm and secure connection.

A further object of the invention is to provide a form of clasp for use upon a wrist cord, which clasp shall be so arranged that 5 Whether the same is open or shut, the wrist cord will remain in complete loop-like formation so that the possibility of the watch being lost from the wrist will be wholly avoided.

A still further object of the invention is to provide a form of clasp which will permlt a spreading or expansion of the wr1st loop to permit the same being re-adlly expanded so that the watch may be placed on or removed from the wearers wrist.

With these objects, and such otherobjects as may hereinafter appear in view, I have devised the particular arrangement of parts hereinafter set forth and more particularly pointed out in the claims appended hereto.

Reference is to be had to the accompanying drawing, forming a part hereof in which Figure 1 is a front elevation of a watch provided with a wrist encircling cord a nd showing my improved clasp in pos tion thereon;

Figure 2 is a view of the rear face of one of the clasp members;

Figure 3 is a view of the rear face of'the male member of the clasp;

Figure 4c is asectional view on the line 4:4 of Figure 2, looking in the direction of the arrows; I

Figure 5 is a sectional view on the line 55 of Figure 3 looking in the direction of the arrows;

Figure 6 is a sectional view on thellne 66 of Figure 1 looking in the direction of the arrows; and

Figure 7 is a front View of the clasp.

Throughout the various views of the drawings, similar reference characters designate similar parts.

In the embodiment of my invention disclosed in. the accompanying drawing, 1 llldk catesa form of wrist watch. The watch herein shown is provided at its oppositeends with a pair of openings 3 and 4 through whicha single continuous cord 5 is loopedasisl shown in Figure 1. This cord may be of silk orsome other like material or it may \be of metal. The two ends of the cord are shown at 6 and 7 and these ends are secured toa pairof fastenerunembers now to be described. One .of these fastener members is shown at .8 and the same is the female member. This fastener member 8 is provided with a continuous tubular guide 9 through which the cord '5 freely passes so that the member 81is movable on that portion of the cord which passes through the guide 9. i

The end 6 of the cord is secured in ,a short tubular socket member 10 which is located adjacent to the edge of the member 8iopposite to that at which the tubular guide 9 is located. In orderto firmly secure the end '6 of the cord in place in the socket 10, I provide said socket with holes 11, through which securing stitches 12 maypass.

It will be seen that there is an intervening space located between the members 9 and 10 and in this space is located an elongated aperture or slot 13. This slot 13'is adapted to receive an elongated stud 14 extending from the inner face of aimalefastener member lf). The male fastener member 15, shown in detail in Figures 3 and 5 is in the nature of a flat plate with curved ends 16 and 1 7.

Extending outwardly from the inner face of the plate is a short socket member 18 in which is securely fitted the end 7of the cord 5. This end 7 of the cord is secured within the socket '18 in alimaznner similar to that by which theopposite end6 onthecord is secured within the socket -10. That is, fastening stitches 19 are utilized, these stitches passing throughholes 20 provided in the socket 18 for their reception. t

It will'thus be seen from theforegoing that the fastening device consistsofa. pair of substantially flat or plate-like members adapted to interlock. Such interlocking is causedby an inter-engagement of a U-shaped spring 21 which isprovided on the inner face of the lapped relationship as is closed clearly in Figure 6, the stud member 1 1 is projected through the aperture 13 and the spring arms 22 and 23 snap into frictional engagement with longitudinal grooves 24 provided in the sides of the stud member 14.

Through the arrangementjust described, the two fastener members 8 and 15 are securely attached together although the same are readily detachable from one another. To facilitate a detachment of one of the parts from the other, the plate 15 is provided with a projecting finger piece 25 on one of its edges which can be readily engaged by the finger nail and lift-ed to cause the stud 2 1 to be drawn out of engagement with the spring arms 22 and 23 and to consequently separate the two members. The spring 21 is preferably made of a section of bent resilient wire and it has its closed or looped end firmly secured to a downwardly bent flange 26 provided on theinner face of the member 8.

The outer ends of the spring arms and 23, shown at 27, are preferably anchored in one of the ends of the plate. It will be noted in Figure 2 that a portion of the member 8 is cut away as at 28 so that the laterally projecting socket member 18 on the plate 1.5 can fit into such cut-out portion and align itself with the member 10. This arrangement materially decreases the thickness of the de vice and produces a uniform appearance on the inner face of the clasp.

It will be seen in Figure 7 that the outer face of the plate member 15 is extremely smooth and free from projecting edges or parts. This smooth outer surface may be set with precious stones or engraved or ornamented in any other way.

The curved edges 16 and 17 permit the plate 15 to conform smoothly to the rounded members 9, 10 andv 18 so that the entire device presents a very pleasing appearance.

From the foregoing, the manner in which the device is used will. be readily understood. In Figure 1, a watch and an attached wrist cord is shown. Here the clasp is in its closed position with the plates overlapped and interengaged as was previously described. When in this position, the wrist cord forms a continuous uniformly looped member, which holds the wrist watch snugly on the wrist. To remove the watch, the fastener members 8 and 15 are separated by raising the plate 15 by lifting the thumb piece 25. Thereupon, the two ends 6 and 7 of the cord are separated and the loop can be enlarged to a great extent to permit the watch to be readily slipped off the wrist. This is facilitated by the fact that the member 8 may be freely slid on the cord since a portion of the cord is slidable through the guide 9.

Having described one embodiment of my invention, it is obvious that the same is not to be restricted thereto, but is broad enough to cover all structures coming within the scope of the annexed claims.

What I claim is 1. A clasp of the class described comprising a pair of fastener members, one of said members having an opening, the other member having a stud adapted to fit therein and detachably unite the members, an attaching cord, means on each of the fastener members for receiving and holding one end of said cord, and a guide member on one of the fastener members through which said cord may freely slide.

2. A clasp composed of a pair of plate-like fastener members, each of said members hav ing a socket member at its rear adapted to re ceive one end of a wrist-ei'nbracing cord, a snap connection between both fastener members for holding the same detachably united, and a guide at the rear of one of the members through which the wrist-embracing cord may freely slide.

3. A clasp composed of a pair of plate-like fastener members, one of said members having a pair of spaced tubular parts on its rear face, one of said tubular parts being adapted to fixedly receive an end of a wrist-embracing cord, the other tubular part being adapted to form a guide through which a part of said cord may slide, means on the other member adapted to fixedly receive the other end of said cord, and means for providing a snap engagement between the two fastener members.

4. A clasp of the character described comprising a pair of flat plate-like members, one of said members having a pair of spaced tubular parts on one of its faces, one of said tubular parts forming a socket for the reception of one end of a wrist-embracing member, the other tubular part forming a guide through which said wrist-embracing member ma y move, means located between the tubular parts for affording a snap connection with the other fastener member and a tubular socket on the last-mentioned fastener member for receiving the opposite end of the wristembracing member.

5. A clasp for uniting the opposite ends of a continuous, looped wrist-embracing cord, said clasp being composed of a pair of overlying clasp men'ibers, one of said members having an opening, the other member having a stud adapted to lit in said opening, means on the perforated member for resiliently engaging the stud on the other member, a securing socket on the rear face of each of the clasp membersfor attaching to the opposite ends of the wrist embracing cord, said socket adapted to lie in alignment when the two clasp members are engaged, and a guide on the perforated member through which a part of the cord may slide.
